Sagot :
Answer:
y = 15 + 0.10x
y = 10 + 0.12x
Step-by-step explanation:
We'll use variable "x" to represent our minutes.
Frank's payment will always $15 no matter what, so there can't be a variable on it. Same with Josie & the $10.
For every minute, x, Frank pays an additional 10 cents with the $15.
For every minute, x, Josie will pay an additional 12 cents with the $10.
Because both equations equal y, we can set them equal to each other to find what value of x that their phone bills will be equal.
15 + 0.10x = 10 + 0.12x
5 = 0.02x
x = 250 minutes
Hope this helps. :)
